One of his slogans for this was "in Roma antiqua, etiam canes Latine locuti sunt" ('in ancient Rome, even the dogs spoke Latin').
Interestingly, the language adverbs are also used in a construction with scire (to know) or intellegere: "Latine scit" (he or she knows Latin), "Graece intellegit" (he or she understands Greek). In English we would definitely think of this as needing a direct object, but Latin allows it as an adverb, to understand "in a Greek way" (perhaps it would make sense to think of it as something like "in a Greek manner" or "from a Greek perspective").
Hopefully I'll get to meet him and speak Latin with him some day.
This is why I only train my dogs in a pure functional language.
Security by obscurity is fundamentally weak, this use wastes bandwidth, and can be destroyed by statistical analysis where the other dogs learn German.
"Map!" ("Bild ab!")
That's also why you teach "sit" first before, "bite the face of the person in front of me" (talking German Shepherds again)
Impressive!
